The reason for me picking this rock was that it was....
-cheap
-easy to get a hold of
-abundant
-its already been exposed to the elements so corrosion is minimum.
-And its slightly magnetic so I could use it in a iron core coil?
-also it hasn't been through a metal factory to be turn into iron yet, its nature "pure".
I don't know fully yet what i'm going to use to replace the magnesium or even if i'm going to replace the magnesium. I might use this rock and magnesium with your mix to see how well it does, its should give more voltage than copper-oxide would? I honestly bought the hematite so that it would be the negative electrode, but later found out that the oxide layer made it more of a positive electrode. I still have lot more testing to do with this rock and many others, its still all new to me. I welcome any input you have
